Get a pointer to an array

[Elad Rosenheim <e_ros@netvision.net.il>]

This question may seem easy, but I haven't been able to find
a solution:

How do I create a normal array, then point an access type to it?
I tried to convert the array 'address attribute to the array access
type,
but it didn't work. I think ADA arrays have some "meta data" before
the data that contains the array bounds, and the 'address attribute
gives the address of the data storage itself. So how can I make the
access
variable point to the array?

This doesn't work:

    type int_array is array(integer <>) of integer;
    type int_access is access int_array;

    function To_Int_Access is new Unchecked_Conversion(
	system.address, int_access);
...

declare
    a : int_array(1..10);
    b : int_access;
begin
    a :=  To_Int_Access(a'address);
...

Please help me with this one.

Thanks,
Elad Rosenheim.
